Abstract

The Co-Ni/Al2O3 catalyst was prepared using incipient wetness impregnation procedure. The effect of different process conditions including reaction temperature, pressure, H2/CO feed ratios and Gas Hourly Space Velocity (GHSV) on the catalytic performance of this impregnated catalyst for CO hydrogenation reaction was investigated in a fixed bed micro reactor. For this purpose reaction conditions were changed as follow: H2/CO ratio from1 to 4, GHSV from 3600 to 6300 and pressure from 1 to 11bar at different temperature from 230 to 260°C. Furthermore the rate of CO hydrogenation over the Co-Ni/ Al2O3 catalyst was investigated. Characterization of the catalysts was performed using various techniques including XRD, BET, SEM and EDS.
